Sensored for 8th scale?

Hey guys,
Still looking around at motors for the MBX. I was thinking about maybe going with a sensored aveox setup. I have previously run an aveox 1409/1.5 and L160 rc esc in an emaxx and it was very nice and smooth, liked it better than the b50 9L although it wasn't quite as fast.

So what do you guys think, maybe go with something like a 1409/1.5 or 1409/2 with an hc160rc esc. Only problem I see is the esc not being able to take an insane amount of amps (100 peak/60 cont.). But also keep in mind this car would be mainly for racing indoor on a tight super high traction clay offroad track (Bumps N Jumps in central PA for anyone familiar) not looking for insane speed runs.
Anyone have any experience with aveox besides their rc7 system?

That 1409 is a rather small motor. If you want more power, i would take a larger motor. Why use the HC160, if the current is a concern? it has got the same currenthandling as the L160.

Perhaps you can take the HC160 and take a lower kv motor (maybe even slightly bigger) and use it on a higher voltage, in order to get the currentdraw down.

The only reason I mentioned that setup is because there is one on ebay right now. My main concearn though is whether a sensored system will be able to perform well in an 8th scale. The main reason I sold the 1409/1.5 and L160rc is because at the time (4-5 years ago) everyone said that a sensored system just wasn't the way to go for a high current fast emaxx.

So heres the question I should have asked first: Are there any drawbacks/advantages in going with a sensored system over a sensorless? If I remember correctly the reason I was told to ditch sensored before years ago was because of max rpm limit or some problem at high rpm.

Thanks,
Pat

If you can find a sensored system comparable in power to a sensorless system, then go for it! The reason why most of us here run sensorless is because there aren't any sensored setups comparable in power to the sensorless setups we run. If such a sensored system came out, I think many of us would at the least be very interested in it!

Yeah you right metal man. I like the sensored part for smoothness and varible timing. I think the sensorless is very smooth to if set up right.

The Aveox is powerful like what we are using the only problem is that their software is not as good as what we are doing. I also doubt that their controller is going to hang in there with the heat.

If you really want to use Aveox, use a 1415, not 1409. If you want a new improved aveox with better efficiency and better magnets, and is sensorless, then buy a Neu Motor. That is exactly what it is. The guy who makes this helped design the Aveox motor. He just took that basic design and built on it with better magnets. The result is one hell of a motor! Here are the motors I own:
Neu
Aveox
Kontronic
Mega
Hacker
Lehner
Nemisis
Feigao
BK
Novak

The Neu is hands down the best(IMO).

@dmc, if you like it being nimble and agile, you might consider a novak HVmaxx on 4S lipo.

What does nimbleness and agility have to do with getting the novak HVmaxx system?

you're forgetting the most important and valuable ingredient i did mentioned;

4S lipo.

Harald-Hans had a movie of his maxx on 4S lipo. It was both agile AND nimble.

I have tried this setup in a hyper 7 and could not get it to work. I had it geared 12:46 and it would thermal after about 3-4 minutes. The power was ok, but could not get it to work at all. Maybe would be ok to bash around the yard with, but I don't see how anyone could get it to work at the track.

Okay, on 4S lipo it should not do that. did you tried another gearing ratio? and did you had a fan mounted? perhaps, because of it being light, a higher gearing would had result in lower temps.

I heard some novaks thermal every time, while others don't.

I would be curious to speak with someone who actually has it working in a buggy and what type of running they are doing(bashing or racing). I tried several different gear ratio's and could not get it to stop from thermalling. I personally don't think it will work for racing, but if someone has done it, lets hear about it.
P.S. I did have the fan mounted.

With Kv=4400 forget about buggy conversion, unless you have 8 or less teeth pinion for 46t spur... or 66-72t spur with pinions you have :)

It is the motor which kills HV performance, wire HV-Novak ESC with good sensored motor (aveox...) and you will see BIG difference.

The kv on that motor isn't actually 4400. I know one of the R&D guys at novak and he told me that the way they test them is different then how the rest of the motors are tested.

I do agree with you that if you put a sensored Aveox on it, the performance would be much better. Why bother though.

i have been told, under load, the hv's are more like 2700 rpms/volt although it might be wrong.
